Biogen (BIIB) Stock Forecast & Price Target
Biogen (BIIB) Analyst Ratings
Bulls say
Biogen's stock has recently experienced a significant uptick of approximately 35% since the beginning of the third quarter of 2025, attributable not only to the broader rally within the biopharmaceutical sector but also to the promising trajectory of its amyloid-beta space, particularly through sales of Leqembi. Key product launches such as Leqembi, Skyclarys, and Zurzuvae have exceeded consensus expectations and are expected to contribute substantially to future revenues, with estimates suggesting potential revenue contributions of $2.5 to $3.0 billion by 2030 as the company addresses market bottlenecks. The company's diverse pipeline, encompassing products for various neurological and rare diseases, positions Biogen for meaningful long-term growth, reinforcing a positive outlook despite anticipated delays in revenue growth until 2026.
Bears say
Biogen's outlook is negatively impacted by anticipated revenue declines from its multiple sclerosis (MS) franchise, which is projected to experience a drop of approximately 5-8% in global revenues following the entry of Sandoz's biosimilar in mid-November 2025, along with additional pressure on Tecfidera in Europe. The company's revenue growth is expected to stagnate with a largely flat revenue compound annual growth rate (CAGR) from 2026-2030 and a negative EBITDA CAGR of -4% during the same period, primarily due to the reduction in royalties from the anticipated biosimilar competition for Ocrevus starting in 2029. Additionally, there are concerns regarding revenue contributions from newer pharmaceutical products like Skyclarys and uncertainties surrounding lupus clinical trials, contributing to the overall negative financial outlook for Biogen.
